I have been slowly convincing myself of the absolute importance of coastal capital cities, and wanted to make good use of the Indonesian's UA. So, although the starting location was decent, I decided to move my warrior along the two rivers to see if I could find a coastal start. Lo and behold - there was a lovely natural wonder. So I got a hill, river, mountain, natural wonder start (in the end the capital extended to 4 luxuries).
I got 8 free faith from a religious CS so I was able to get the first pantheon, which went straight into One with Nature. I then realized I was fairly close to the ominous prospects of the Ottomans and Rome. I made the decision early to settle one city more or less where I had started, but on the other side of the river so as not to piss off neighbours. There was some good dirt towards Suleiman but I judged this wasn't worth the diplo penalty (I really have learnt a lot from Small Piety diplomacy). I did steal a worker from a CS and Rome, but quickly made peace.
Intermittent working of the natural wonder helped speed up SPs at certain key points. I went Tradition, to make sure I expanded my cultural borders nice and quickly (good decision, I think), but I then decided to go Liberty, as I hoped to be settling a few cities on nice little Spice Islands. Furthermore, liberty made a bit more sense given that I was trying for a CV, so I'd be able to use a GE for a wonder. From Pottery I went straight for Sailing and bought a quick a trireme, to see if there actually any islands worth settling. Then I went Trapping and Mining for the Luxes.
The trireme brought back positive news - there were two close islands with unique luxuries, plus a big continent with about 6 truffles in trireme view. I sent my units and scouts over there and found there were 2-3 really good spots on that new continent, on which sat Ethiopia but blocked by jungle and mountains. The culture from the natural wonder helped get my settler out reasonably early, and I quickly produced another 2. Getting the units, workers and settlers over there was a pain, even escorted by the trireme, due to barb archers. Eventually we got over, and I settled my first city on the big continent. With the money from the free luxuries (sold to my friend Rome) I was able to buy Libraries and more settlers. I had liberty finished and NC built by about T80, with 7 cities. Not sure in retrospect whether settling so many cities was a good idea, but they all offered unique luxuries and would deny Ethiopia becoming the cultural/science powerhouse they often can be. I decided at this point to use the liberty finisher for a GS instead of a GE, as it would help me get to the important cultural wonder techs early enough. I'm not sure if this was a good decision.
By this time I had already got my own religion, and chose Pagodas (although looking back the production boost would have surely been more useful). Noone on my island had a religion yet, so I was licking my lips at being able to convert the whole island. I set all my cities to build Shrines, Temples and Candis. But this is where I missed Small Piety. As I was beelining Acoustics to get Rationalism with my next SP, missionaries and pagodas ended up being pretty expensive. I used my second prophet to try to convert Rome and the Ottomans although it didn't manage to get the elusive diplo modifier on the Ottomans before they had expanded. And then came the missionary spam of Ethiopia. A few turns later Ottomans forward settled me and denounced me on the same turn. On the positive side, I did manage to flip quite a few cities until the late game which was positive for Tithe. I was also able to get Cathedrals in my satellite cities using Ethiopia's religion.
As soon as I got Acoustics, I tried to hard build the Sistine Chapel. Used to using tradition, I was dismayed by how long it was going to take (about 25 turns), but tried anyway. I was spying on Morocco and, when it got down to about 8 turns, noticed that they were building it. Luckily I able to find a way to beat them by 1 turn. Next stop Printing Press for the Leaning Tower. One turn before I got into Printing Press it was taken, so it would have problably trolled me had I gone there first. Globe Theatre then went in the next few turns, so things weren't looking too good.
At this stage I decided that my best chance of CV would be to make a beeline for Exploration, as many civs had Aesthetics so I didn't fancy my chances of Uffizi. My next two policies were therefore the 2nd policy of rationalism and then exploration opener. I got the Louvre, and spammed about 20 archeologists in all my cities, getting all the sites on my two continents.
At this point is when it started to a bit pear shaped. In previous games, I had always had too many cultural policies by the end (after completing Aesthetics, Freedom and Rationalism), so I foolishly decided to go a little further into Exploration, as I had many coastal cities (crazily I thought I might even get to the end and get some hidden sites). However, this was a big mistake as my culture was not moving anywhere near fast enough. There was only one CS in the game, which fortunately I was allied with, but I was unable to propose the World's Fair and missed out on SoL and Sidney OH. So in the end I had to leave Rationalism as it was, and got through Aesthetics and Freedom FAR too late for my liking.
I was able to build PT in my second city, and abused the research agreements. However, not used to playing this wide, I overestimated how quickly I would be at the Internet, and got there far quicker than I had estimated. Luckily I was able to get Eiffel Tower and the CN Tower, which provided free Broadcast Towers in most of my cities just I was hitting Internet. I hadn't used Oxford though as I was planning to use it to get the Internet, so I had to use that for Globalization. I thought at least this would help me try and influence World Congress matters more effectively. I basically failed at this though, not able to push through World Religion and having my luxuries banned (really, seriously, how can pepper provide no happiness?)
Then Morocco declared on me, which was a right pain, as they were one of the two civs that I needed to GM bomb. What followed was a tedious nuclear submarine/battleship slog to get GMs into their territory (luckily, I had saved up a lot of faith for GMs, so their production wasn't the problem, rather their offshore concert tours
). India was the other culture leader, and I was able to get her to help me defend. I used the final GMs on them, and fortunately did manage to scrape a CV just 5 turns before Gandhi BOTH completed his final spaceship part AND became influential with Morocco.
So anyway...I am happy with the victory (CV obviously being much more difficult than Diplo and Science on Deity), and in a lot of ways I made some good decisions, but I also made some pretty bad ones as well. Some of these are as follows. If I had optimised the use of my GSs and RAs I could have probably got up to the Internet about 30 turns earlier. I should have focused more on production in my capital (mines instead of farms), so I could get the important wonders and buildings in a more respectable time. I should have gone into Aesthetics faster, without being tempted by Exploration. I should have focused more on culture buildings in my satellite cities instead of public schools and research labs. This would have helped me get my Hermitage faster. I probably shouldn't have settled cities 6 and 7. It should have also been a priority for me to get more CSs under my wing earlier in order to pass the World Religion vote. But that's the thing about a CV, there are so many things to do and no time/production/gold to do it. It was quite a difficult map actually, with two super aggressive neighbours next to me, and two big cultural powerhouses in India and Ethiopia left relatively unmolested, as well as only one cultural CS.
